When it comes to caring for your landscaping, the use of fertilizer can
be critical for ensuring the
success of your plants and grass. If you are caring for a lawn or garden for the first time, then you may
have questions about fertilizers and which one is right for your needs.
Before heading to your local garden center or hardware store in San Jose
for fertilizer, it’s important to understand what an NPK ratio is.

N, P, and K, are the chemical symbols for nitrogen, phosphorus, and potassium.
In terms of fertilizer, the NPK ratio describes the relative amounts of
these 3 chemicals. No matter what type of fertilizer you buy, the label
will include information about the nutrients that it contains. Also, every
fertilizer will contain at least 1 of these 3 chemicals and will be marked
with a “0” in the ratio for any that it does not contain.
